The RGL13 fall arrest lanyard like the RGL1 is an industry standard, and normally the minimum equipment issued with a harness for working at height. The 40kN webbing used in the manufacture provides greater strength compared to other webbing and systems. The additional benefit of adjustability allow for greater flexibility. The lanyard length can be adjusted to suit the application. Potential trip hazard can be avoided and potential free fall distance can be reduced which is less possible with a non-adjusting lanyard.

This lanyard should be used when the operative is working from a static position, connected to a fixed anchor point. If movement between anchorages is required, a twin leg lanyard should be used (RGL3), to provide constant protection.
